A. the gas particles move faster and collide more frequently, which causes an increase in pressure.
Increasing temperature increases the energy of the gas, which causes the kinetic energy of the molecules to increase.
The change that will always result in an increase in the gravitational force between two objects is increasing the masses of the objects and decreasing the distance between the objects.
Answer:
As animals get older, their bodies begin to change as well as their instincts and priorities. They get bigger and might adapt or develop.
Answer:
The force of static friction acting on the luggage is, Fₓ = 180.32 N
Explanation:
Given data,
The mass of the luggage, m = 23 kg
You pulled the luggage with a force of, F = 77 N
The coefficient of static friction of luggage and floor, μₓ = 0.8
The formula for static frictional force is,
Fₓ = μₓ · η
Where,
η - normal force acting on the luggage 'mg'
Substituting the values in the above equation,
Fₓ = 0.8 x 23 x 9.8
= 180.32 N
Hence, the minimum force require to pull the luggage is, Fₓ = 180.32 N
Solar it is the cheapest and widely used energy source
